The performance limitations of RAID5 or 6 vs RAID10 are mitigated by the number of spindles. If you have 8 or more drives in your array, the performance difference disappears. This, of course assumes a true hardware RAID controller and NOT software.

I believe that RAID6 comes under the same performance limitations of RAID5. For applications where data performance must be the highest, RAID10 is your best option. The problems of the other RAIDs can be seen here: http://www.baarf.com/

OK, before a disussion starts, I need to say that RAID 6 is important for us (high security), and also performance. With these tests, I'd recommend Areca. Maybe you have another needs to prefer LSI.
